Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixture at the surge tank, but only when the
engine is cool.

You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing the pressure cap, press down and
turn it clockwise until you hear a clicking sound.
Make sure the cap is hand-tight and fully seated.

coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. SeeEngine
Compartment Overview on page 6-12for more
information on location.
Engine Overheating
You will nd a COOLANT OVER TEMP message or an
ENGINE HOT, STOP ENGINE message displayed in
the Driver Information Center (DIC). SeeDIC Warnings
and Messages on page 3-63. You will also hear a
chime.
There is also an engine coolant temperature gage on
the instrument panel cluster. SeeEngine Coolant
